And, as shown in Figure 6, respectively accommodate terminal 153 and comprise as the elastic arm 153a of the first terminal parts and as the fixedly arm 153b of second terminal component.Above-mentioned elastic arm 153a is the parts that work as spring portion, this elastic arm 153a is the elongated member with roughly L shaped flat shape, and the position of the short side direction of the close main part 111 in terminal accommodating opening 154 (terminal accommodating opening 154 a vertically) end, the cardinal extremity of this elastic arm 153a is crooked and be connected with the fixing lateral margin of arm 153b, and this elastic arm 153a is positioned at the side of said fixing arm 153b.And, above-mentioned elastic arm 153a is a kind of cantilever beam, its free end is as the elastic contact part 153a1 that is formed at or is connected near first contact site of end or end, and this free end is positioned at the other end of the short side direction of main part 111 terminal accommodating opening 154, close.That is to say that above-mentioned elastic arm 153a has the flat shape that comprises bend 153a2, the mode bending that bend 153a2 gives prominence to towards the side of said fixing arm 153b with cardinal extremity and the part between the end of elastic arm 153a.And above-mentioned elastic contact part 153a1 is by elastic arm 153a strain, goes up elastic displacement at the long side direction of main part 111 (terminal accommodating opening 154 laterally).

In addition, said fixing arm 153b is the elongated member that extends point-blank on the short side direction of main part 111, is stained with enhancement layer 116, coverlay 117 and basement membrane 115 at the fixing two ends of arm.Therefore, said fixing arm 153b is higher with above-mentioned elastic arm 153a phase specific rigidity, and fixedly arm as in fact not the rigid portion of strain work.In addition, the lateral margin of said fixing arm 153b be formed with the opposed mode of above-mentioned elastic contact part 153a1 outstanding, as the rigidity contact site 153b1 of second contact site.This rigidity contact site 153b1 is nonelastic in fact on the long side direction of main part 111 (terminal accommodating opening 154 laterally) to be fixed with displacement.In addition, above-mentioned rigidity contact site 153b1 is not necessarily from the outstanding shape of the lateral margin of fixing arm 153b, also can be from the fixing recessed shape of lateral margin of arm 153b, perhaps also can be and the fixing shape of the lateral margin formation straight line of arm 153b.

And, above-mentioned terminal accommodating opening 154 comprise be formed on elastic arm 153a and fixedly the outstanding terminal accommodating opening of the conduct between the arm 153b interior side opening 154a and be formed on the outer openings 154b in the elastic arm 153a outside.Side opening 154a is in the part of accommodating terminal 153 outstanding terminal 53 of ccontaining insertion when docking with the outstanding terminal 53 of male connector 1 in above-mentioned, and above-mentioned outer openings 154b is the part of the above-mentioned elastic arm 153a of permission displacement.

And the size of the inside part of the bend 153a2 of above-mentioned interior side opening 154a forms the side dimension greater than the top ends 53b of outstanding terminal 53.Thus, accommodating terminal 153 when docking with outstanding terminal 53, in outstanding terminal 53 can enter swimmingly in the side opening 154a.In addition, the size between the elastic contact part 153a1 of interior side opening 154a and the rigidity contact site 153b1 is less than the width dimensions of the interior side opening 154a of bend 153a2, and less than diameter of section or the width dimensions of outstanding terminal 53.Therefore, interior side opening 154a is more more little near elastic contact part 153a1 width dimensions, when the outstanding terminal 53 in being housed in the side opening 154a moves with respect to the part between elastic contact part 153a1 and the rigidity contact site 153b1, interval between elastic contact part 153a1 and the rigidity contact site 153b and the side surface part 53c butt of outstanding terminal 53, thus the interval of elastic contact part 153a1 and rigidity contact site 153b is expanded.Under this situation, because fixedly arm 153b is essentially rigid body, 153b1 is unshift for the rigidity contact site, and elastic arm 153a flexibly is out of shape, flexibly displacement of elastic contact part 153a1.Therefore, outstanding terminal 53 is subjected to the contact pressure of elastic arm 153a.

In addition, owing to be positioned at an elastic arm 153a who accommodates terminal 153 to the lateral outer side displacement, and be positioned at another fixedly arm 153b that accommodates terminal 153 not to the lateral outer side displacement, namely expand to the displacement of lateral outer side and diminish so accommodate terminal 153.Therefore, adjacent accommodate terminal 153 and can not contact with each other, thus can constriction this accommodate the spacing of terminal 153.

In addition, each conductive pattern 151 accommodate terminal 153 about the horizontal center line of each conductive pattern 151 line symmetry not, but have asymmetrical shape.That is to say that in each terminal accommodating opening 154, because elastic arm 153a only is arranged in the horizontal side of terminal accommodating opening 154 (being the right side at example shown in Figure 6), each outstanding terminal 53 is subjected to the contact pressure of a direction.Therefore, if all the shape of accommodating terminal 153 and terminal accommodating opening 154 of conductive pattern 151 is all identical, the male connector 1 that then has outstanding terminal 53 is subjected to towards the pushing force of a direction (being left example shown in Figure 6) from recessed connector 101, in addition, because recessed connector 101 is subjected in the opposite direction the counter-force of (example shown in Figure 6 for right-hand) from male connector 1, the state of the male connector 1 of butt joint and recessed connector 101 becomes unstable mutually.

Therefore, in the present embodiment, the tabular that engages with outstanding terminal 53 is accommodated the spring portion of terminal 153, and namely elastic arm 153a produces the elastic force towards the transverse center of recessed connector 101.Particularly, as shown in Figure 4, be line symmetrical manner pattern conductive pattern 151 with the cross central line C with respect to recessed connector 101, accommodate terminal 153 and terminal accommodating opening 154 with formation.In example shown in Figure 4, be arranged in the conductive pattern 151 on center line C right side, elastic arm 153a is positioned at the fixedly right side of arm 153b, and the elastic force that elastic arm 153a produces is towards left (direction of center line C).On the other hand, be arranged in the conductive pattern 151 in center line C left side, elastic arm 153a is positioned at the fixedly left side of arm 153b, and the elastic force that elastic arm 153a produces is towards right-hand (direction of center line C).Thus, the male connector 1 of butt joint and the state of recessed connector 101 become stable mutually, have stably kept all outstanding terminal 53 and have accommodated contacting of terminal 153.

In the present embodiment, accommodating terminal 153 and not necessarily be defined in Fig. 4～example shown in Figure 6, also can be any plane shape shown in Fig. 7 A～Fig. 7 F.In addition, the below of Fig. 7 A～Fig. 7 F is corresponding with the place ahead and the rear of recessed connector 101 with the top.

In the example shown in Fig. 7 A, accommodate terminal 153 and do not comprise and fixedly arm 153b as second terminal component only comprise the elastic arm 153a as the first terminal parts.This elastic arm 153a is the cantilever beam shape parts that extend point-blank, does not comprise bend 153a2.In addition, the free end of above-mentioned elastic arm 153a namely is positioned at end or is positioned at the strain by elastic arm 153a near the elastic contact part 153a1 of end, goes up elastic displacement at the long side direction of main part 111 (terminal accommodating opening 154 laterally).

In addition, in the example shown in Fig. 7 A, the space on the right side of elastic arm 153a and the space in left side are equivalent to outer openings 154b and the interior side opening 154a in the example of Fig. 4～shown in Figure 6 respectively.Should in side opening 154a be in the part that should give prominence to terminal 53 of accommodating terminal 153 ccontaining insertion when dock with the outstanding terminal 53 of male connector 1, above-mentioned outer openings 154b is the part of the above-mentioned elastic arm 153a of permission displacement.

And, because the shape that the left of elastic contact part 153a1 tool directed graph is outstanding, outstanding terminal 53 in entering in the side opening 154a moves along elastic arm 153a, when elastic contact part 153a1 moves with respect to the end of elastic arm 153a, because side surface part 53c and the elastic contact part 153a1 butt of outstanding terminal 53, elastic arm 153a flexibly is out of shape, the right-hand elastic displacement of elastic contact part 153a1 in the figure.Therefore, outstanding terminal 53 is subjected to the contact pressure of elastic arm 153a.

In addition, in the example shown in Fig. 7 A, with Fig. 4～example shown in Figure 6 similarly, accommodate the cross central line line symmetry that terminal 153 also is not in relation to each conductive pattern 151, but have asymmetrical shape.That is to say that in each terminal accommodating opening 154, because elastic arm 153a only is arranged in the horizontal side (being the right side at the example shown in Fig. 7 A) of side opening 154a, each outstanding terminal 53 is subjected to the contact pressure of a direction.Therefore, with Fig. 4～example shown in Figure 6 similarly, accommodate the spring portion of terminal 153, namely the elastic force that produces of elastic arm 153a is towards the transverse center of recessed connector 101.Particularly, as shown in Figure 4, be line symmetrical manner pattern conductive pattern 151 with the cross central line C with respect to recessed connector 101, form with this and accommodate terminal 153 and terminal accommodating opening 154.That is to say that the conductive pattern 151 that is positioned at center line C right side has the shape shown in Fig. 7 A, and be positioned at the shape of the mirror image of shape that reversed about conductive pattern 151 on the left of the center line C has, shown in Fig. 7 A.

In addition, in the example shown in Fig. 7 B, with example shown in Fig. 7 A similarly, the space on the right side of elastic arm 153a and the space in left side are equivalent to outer openings 154b and the interior side opening 154a in the example of Fig. 4～shown in Figure 6 respectively.Should in side opening 154a be in the part that should give prominence to terminal 53 of accommodating terminal 153 ccontaining insertion when dock with the outstanding terminal 53 of male connector 1, above-mentioned outer openings 154b is the part of the above-mentioned elastic arm 153a of permission displacement.

And bend 153a2 to be protruding into the mode bending in the outer openings 154b, the result, and the width of interior side opening 154a becomes big at the base end side of elastic arm 153a, and more more narrow near elastic contact part 153a1 width towards the end of elastic arm 153a.In addition, elastic contact part 153a1 is outstanding to the left of figure.Therefore, when the outstanding terminal 53 in entering in the side opening 154a relatively moves towards the end of the elastic arm 153a that forms elastic contact part 153a1, because side surface part 53c and the elastic contact part 153a1 butt of outstanding terminal 53, elastic arm 153a flexibly is out of shape, the right-hand elastic displacement of elastic contact part 153a1 in the figure.Therefore, outstanding terminal 53 is subjected to the contact pressure of elastic arm 153a.

In addition, in the example shown in Fig. 7 B, with Fig. 4～example shown in Figure 6 similarly, accommodate the cross central line line symmetry that terminal 153 also is not in relation to each conductive pattern 151, but have asymmetrical shape.That is to say that in each terminal accommodating opening 154, because elastic arm 153a only is arranged in the horizontal side (being the right side at the example shown in Fig. 7 B) of side opening 154a, each outstanding terminal 53 is subjected to the contact pressure of a direction.Therefore, with Fig. 4～example shown in Figure 6 similarly, accommodate the spring portion of terminal 153, namely the elastic force that produces of elastic arm 153a is towards the transverse center of recessed connector 101.Particularly, as shown in Figure 4, be line symmetrical manner pattern conductive pattern 151 with the cross central line C with respect to recessed connector 101, form with this and accommodate terminal 153 and terminal accommodating opening 154.That is to say that the conductive pattern 151 that is positioned at center line C right side has the shape shown in Fig. 7 B, the shape of the mirror image of shape that reversed about the conductive pattern 151 that is positioned at center line C left side has, shown in Fig. 7 B.

In the example shown in Fig. 7 C, with example shown in Fig. 4～6 similarly, accommodate terminal 153 and comprise as the elastic arm 153a of the first terminal parts and as the fixedly arm 153b of second terminal component.Above-mentioned elastic arm 153a be comprise bend 153a2 and base end part, have a roughly elongated member of L shaped flat shape, this elastic arm's base end part is crooked and be connected with the fixing lateral margin of arm 153b, and this elastic arm is positioned at the side of said fixing arm 153b.And, above-mentioned elastic arm 153a is a kind of cantilever beam, its free end is as the elastic contact part 153a1 that forms or be connected first contact site of end or terminal vicinity, the strain of elastic contact part 153a1 by elastic arm 153a goes up elastic displacement at the long side direction of main part 111 (terminal accommodating opening 154 laterally).In addition, on the lateral margin of said fixing arm 153b with the opposed position of elastic contact part 153a1 be rigidity contact site 153b1, but this rigidity contact site 153b1 forms with the fixing lateral margin of arm 153b and is positioned on the straight line.

And, in the example shown in Fig. 7 C, above-mentioned terminal accommodating opening 154 comprise be formed on elastic arm 153a and fixedly the interior side opening 154a between the arm 153b, be formed on the outer openings 154b in the elastic arm 153a outside.Above-mentioned interior side opening 154a is accommodating terminal 153 ccontaining part that should outstanding terminal 53 when docking with the outstanding terminal 53 of male connector 1, and above-mentioned outer openings 154b is the part that allows above-mentioned elastic arm 153a displacement.

In addition, the otherwise structure in the example shown in Fig. 7 C is identical with the example shown in Fig. 7 B with operation, so omit its explanation.

In the example shown in Fig. 7 D, the flat shape level of accommodating terminal 153 is asymmetric but vertically symmetrical, and does not comprise the fixedly arm 153b as second terminal component, only comprises the elastic arm 153a as the first terminal parts.This elastic arm 153a is the beam with both ends built-in shape parts that extend point-blank, does not comprise bend 153a2.Elastic arm's two ends with remain in around conductive pattern 151 be connected, near terminal or terminal elastic contact part 153a1 is by the strain of elastic arm 153a, goes up elastic displacement at the long side direction of main part 111 (terminal accommodating opening 154 laterally).

In addition, in the example shown in Fig. 7 D, the space on the right side of elastic arm 153a and the space in left side are equivalent to outer openings 154b and the interior side opening 154a in the example of Fig. 4～shown in Figure 6 respectively.Should in side opening 154a be in the part that should give prominence to terminal 53 of accommodating terminal 153 ccontaining insertion when dock with the outstanding terminal 53 of male connector 1, above-mentioned outer openings 154b is the part of the above-mentioned elastic arm 153a of permission displacement.

And because the outstanding shape of the left of elastic contact part 153a1 tool directed graph, the outstanding terminal 53 in entering in the side opening 154a moves along elastic arm 153a.When elastic contact part 153a1 moved with respect to the center of elastic arm 153a, because side surface part 53c and the elastic contact part 153a1 butt of outstanding terminal 53, elastic arm 153a flexibly was out of shape, the right-hand elastic displacement of elastic contact part 153a1 in the figure.Therefore, outstanding terminal 53 is subjected to the contact pressure of elastic arm 153a.

In addition, in the example shown in Fig. 7 D, with Fig. 4～example shown in Figure 6 similarly, accommodate the cross central line line symmetry that terminal 153 also is not in relation to each conductive pattern 151, but have asymmetrical shape.That is to say that in each terminal accommodating opening 154, because elastic arm 153a only is arranged in the side (being the right side at the example shown in Fig. 7 D) of side opening 154a, each outstanding terminal 53 is subjected to the contact pressure of a direction.Therefore, with Fig. 4～example shown in Figure 6 similarly, accommodate the spring portion of terminal 153, namely the elastic force that produces of elastic arm 153a is towards the transverse center of recessed connector 101.Particularly, as shown in Figure 4, be line symmetrical manner pattern conductive pattern 151 with the cross central line C with respect to recessed connector 101, form with this and accommodate terminal 153 and terminal accommodating opening 154.That is to say that the conductive pattern 151 that is positioned at center line C right side has the shape shown in Fig. 7 D, the shape of the mirror image of shape that reversed about the conductive pattern 151 that is positioned at center line C left side has, shown in Fig. 7 D.

In the example shown in Fig. 7 E, the flat shape level of accommodating terminal 153 is asymmetric but vertically symmetrical, does not comprise the fixedly arm 153b as second terminal component, only comprises the elastic arm 153a as the first terminal parts.This elastic arm 153a comprises bend 153a2, and this elastic arm is the combination that wedge shape beam-like element or pair of curved become L shaped member, this elastic arm's two ends with remain in around conductive pattern 151 be connected, near central part or the central part elastic contact part 153a1 is by the strain of elastic arm 153a, goes up elastic displacement at the long side direction of main part 111 (terminal accommodating opening 154 laterally).

In addition, in the example shown in Fig. 7 E, the space on the right side of elastic arm 153a and the space in left side are equivalent to outer openings 154b and the interior side opening 154a in the example of Fig. 4～shown in Figure 6 respectively.Should in side opening 154a be in the part that should give prominence to terminal 53 of accommodating terminal 153 ccontaining insertion when dock with the outstanding terminal 53 of male connector 1, above-mentioned outer openings 154b is the part of the above-mentioned elastic arm 153a of permission displacement.

And, because bend 153a2 is to protrude into the mode bending in the outer openings 154b near the two ends of elastic arm 153a, and elastic contact part 153a1 leaves the outstanding bight of central part (to the left of figure), the width of interior side opening 154a becomes big at the base end side of elastic arm 153a, and more more narrow near elastic contact part 153a1 width towards the center of elastic arm 153a.Therefore, when the outstanding terminal 53 in entering in the side opening 154a relatively moves towards the center of the elastic arm 153a that has formed elastic contact part 153a1, because side surface part 53c and the elastic contact part 153a1 butt of outstanding terminal 53, elastic arm 153a flexibly is out of shape, the right-hand elastic displacement of elastic contact part 153a1 in the figure.Therefore, outstanding terminal 53 is subjected to the contact pressure of elastic arm 153a.

In addition, in the example shown in Fig. 7 E, with Fig. 4～example shown in Figure 6 similarly, accommodate the cross central line line symmetry that terminal 153 also is not in relation to each conductive pattern 151, but have asymmetrical shape.That is to say that in each terminal accommodating opening 154, because elastic arm 153a only is arranged in the horizontal side (being the right side at the example shown in Fig. 7 E) of side opening 154a, each outstanding terminal 53 is subjected to the contact pressure of a direction.Therefore, with Fig. 4～example shown in Figure 6 similarly, accommodate the spring portion of terminal 153, namely the elastic force that produces of elastic arm 153a is towards the transverse center of recessed connector 101.Particularly, as shown in Figure 4, be line symmetrical manner pattern conductive pattern 151 with the cross central line C with respect to recessed connector 101, form with this and accommodate terminal 153 and terminal accommodating opening 154.That is to say that the conductive pattern 151 that is positioned at center line C right side has the shape shown in Fig. 7 E, the shape of the mirror image of shape that reversed about the conductive pattern 151 that is positioned at center line C left side has, shown in Fig. 7 E.

In the example shown in Fig. 7 F, the asymmetric but vertical symmetry of the flat shape level of accommodating terminal 153 comprises as the elastic arm 153a of the first terminal parts and as the fixedly arm 153b of second terminal component.Above-mentioned elastic arm 153a is the combination that tapered beam shape parts or pair of curved become L shaped member, and elastic arm's two ends are connected with conductive pattern 151 around remaining in, and the elastic arm is positioned at the side of said fixing arm 153b.And, above-mentioned elastic arm 153a is a kind of beam with both ends built-in (double bracing beam), the central part of above-mentioned elastic arm 153a or be formed near its central part the strain of elastic contact part 153a1 by elastic arm 153a is gone up elastic displacement at the long side direction of main part 111 (terminal accommodating opening 154 laterally).In addition, on the lateral margin of said fixing arm 153b with the opposed position of elastic contact part 153a1 be rigidity contact site 153b1, but this rigidity contact site 153b1 forms with the fixing lateral margin of arm 153b and is positioned on the straight line.

And, in the example shown in Fig. 7 F, above-mentioned terminal accommodating opening 154 comprise be formed on elastic arm 153a and fixedly the interior side opening 154a between the arm 153b, be formed on the outer openings 154b in the elastic arm 153a outside.Side opening 154a is accommodating the terminal 153 ccontaining part that should give prominence to terminal 53 when dock with the outstanding terminal 53 of male connector 1 in above-mentioned, and above-mentioned outer openings 154b is the part of the above-mentioned elastic arm 153a of permission displacement.

In addition, the otherwise structure in the example shown in Fig. 7 F is identical with the example shown in Fig. 7 E with operation, so omit its explanation.

The action of docking of male connector 1 with said structure and recessed connector 101 then, is described.

Fig. 8 is first view of docking operation of first connector and second connector of expression embodiment of the present invention, and Fig. 9 is second view of representing the docking operation of first connector of embodiment of the present invention and second connector.Wherein, Fig. 8 A and Fig. 9 A are the observed vertical view of installed surface side from second connector, and Fig. 8 B and Fig. 9 B are the drawing in side sectional elevation of the side surface part of the outstanding terminal among Fig. 8 A and Fig. 9 A.

In male connector 1, connection gasket on the afterbody 58 of conductive pattern 51 utilizes welding etc. and is formed on first substrate surface is connected, the part utilization welding etc. of strengthening the bottom surface of carriage 56 is connected with fixed bolster on being formed on first substrate surface, thereby male connector 1 is installed on the surface of first substrate.In addition, in recessed connector 101, connection gasket on the afterbody 158 of conductive pattern 151 utilizes welding etc. and is formed on second substrate surface is connected, the part utilization welding etc. of strengthening the bottom surface of carriage 156 is connected with fixed bolster on being formed on second substrate surface, thereby recessed connector 101 is installed on the surface of second substrate.In addition, in Fig. 8 and Fig. 9, for convenience of description, diagram is omitted first substrate and second substrate.

The interface that operating personnel make the interface of male connector 1 and recessed connector 101 opposed to each other, male connector 1 is descended along the butt joint direction towards recessed connector 101, and the interface of male connector 1 is contacted with the interface of recessed connector 101 or closely contact.

Thus, become the state shown in Fig. 8 A and Fig. 8 B.Under this situation, engagement lugs 56a on the reinforcement carriage 56 that is formed on male connector 1 left and right sides is entered in the coupling opening 159 on the reinforcement carriage 156 of the left and right sides that is formed on recessed connector 101, and carry out male connector 1 and recessed connector 101 along horizontal location.In addition, each in the outstanding terminal 53 enter correspondence accommodate terminal 153 inboards, be formed on elastic arm 153a and fixedly in the interior side opening 154a between the arm 153b.Shown in Fig. 8 A, because the size of the inside part of the bend 153a2 of interior side opening 154a forms the side dimension greater than the top ends 53b of outstanding terminal 53, outstanding terminal 53 can enter in the interior side opening 154a swimmingly.

Then, operating personnel press among Fig. 8 A and Fig. 8 B shown in the arrow A, and male connector 1 is forwards slided with respect to recessed connector 101.That is, male connector 1 is forwards advanced with respect to recessed connector 101, so that the surface of the surface of male connector 1 and recessed connector 101 contacts with each other or approach.Under this situation, each outstanding terminal 53 enters among the corresponding interior side opening 154a that accommodates terminal 153 inboards smoothly, and owing to the engagement lugs 56a of left and right sides enters in the coupling opening 159 of left and right sides, so male connector 1 can not misplace with respect to recessed connector 101.

And shown in Fig. 9 A and Fig. 9 B, if male connector 1 is finished with docking of recessed connector 101, then each outstanding terminal 53 enters the corresponding elastic contact part 153a1 that accommodates terminal 153 and the part between the rigidity contact site 153b1.

Thus, in respectively accommodating terminal 153, the interval between elastic contact part 153a1 and the rigidity contact site 153b and the side surface part 53c butt of outstanding terminal 53, thus the interval of elastic contact part 153a1 and rigidity contact site 153b is expanded.And the elastic force effect pushing elastic contact part 153a1 of elastic arm 153a is with the side surface part 53c against outstanding terminal 53, and the side surface part 53c of outstanding terminal 53 flexibly is clamped in elastic contact part 153a1 and rigidity contact site 153b1.Thus, contact and set up outstanding terminal 53 and corresponding electrical connection of accommodating between the terminal 153 reliably.

In addition, when outstanding terminal 53 entered part between elastic contact part 153a1 and the rigidity contact site 153b1, only the side of its side surface part 53c (right side or left side) was subjected to the pushing force from elastic arm 153a, namely contacts pressure.But, as previously mentioned, to accommodate in the terminal 153 at each, the contact pressure that elastic arm 153a produces is towards the transverse center of recessed connector 101, so male connector 1 and recessed connector 101 keep stable.

In addition, when outstanding terminal 53 entered part between elastic contact part 153a1 and the rigidity contact site 153b1, outstanding terminal 53 slipped over the rigidity contact site 153b1 that gives prominence to from the fixing lateral margin of arm 153b, so the counter-force of being subjected to.And this counter-force is delivered to operating personnel's finger with the click propagated sensation of rattling away.That is to say that the side surface part 53c by outstanding terminal 53 slips at rigidity contact site 153b1 and produces the click sense of rattling away.

And, shape of cross section at the side surface part 53c that gives prominence to terminal 53 is under the situation of longitudinal size greater than lateral dimension, because it is big that the contact area between elastic contact part 153a1 and the rigidity contact site 153b1 becomes, contact resistance diminishes, and by elastic contact part 153a1 and rigidity contact site 153b1 clamping terminal stably.

And, at the shape of cross section of the side surface part 53c of outstanding terminal 53 for having the tip in forward direction, namely, comprise under the situation of rake in forward direction, because terminal can easily enter part between elastic contact part 153a1 and the rigidity contact site 153b1, so can easily carry out the operation of docking of male connector 1 and recessed connector 101.

And shown in Fig. 9 A and Fig. 9 B, if male connector 1 is finished with docking of recessed connector 101, then engagement lugs 56a is accommodated and is remained in the maintaining part 159a.Thus, carry out the location of male connector 1 and recessed connector 101 reliably.

In addition, make male connector 1 action opposite with the 101 butt joint actions of recessed connector by execution, can remove docking of male connector 1 and recessed connector 101, so omission is to this explanation.

Like this, in the present embodiment, the recessed connector 101 that docks with male connector 1 has the tabular conductive part 150 that comprises a plurality of conductive patterns 151, in the conductive pattern 151 each comprise engage with the outstanding terminal 53 of male connector 1 accommodate terminal 153, respectively accommodate terminal 153 comprise the interior side opening 154a that accommodates outstanding terminal 53, be positioned at the fixing side of arm 153b beam shape elastic arm 153a, be formed on the elastic contact part 153a1 on the elastic arm 153a.If the outstanding terminal 53 in being housed in the side opening 154a relatively moves towards elastic contact part 153a1, then elastic arm 153a produces the elastic force towards the transverse center of recessed connector 101.
